### Modify the OpenAPI schema

Now you can add the ReDoc extension, adding a custom `x-logo` to the `info` "object" in the OpenAPI schema:

```Python hl_lines="22-24"
{!../../../docs_src/extending_openapi/tutorial001.py!}
```

### Cache the OpenAPI schema

* `GET` : pour lire de la donnée.
* `PUT` : pour mettre à jour de la donnée.
* `DELETE` : pour supprimer de la donnée.

Donc, dans **OpenAPI**, chaque méthode HTTP est appelée une "opération".

Nous allons donc aussi appeler ces dernières des "**opérations**".


#### Définir un *décorateur d'opération de chemin*

```Python hl_lines="6"
{!../../../docs_src/first_steps/tutorial001.py!}
```

And we return the scopes as part of the JWT token.

!!! danger
    For simplicity, here we are just adding the scopes received directly to the token.

    But in your application, for security, you should make sure you only add the scopes that the user is actually able to have, or the ones you have predefined.

=== "Python 3.10+"

```

!!! tip
    Here we are creating the models with an `id`.

    We didn't explicitly specify an `id` attribute in the Peewee models, but Peewee adds one automatically.

    We are also adding the magic `owner_id` attribute to `Item`.

### Create a `PeeweeGetterDict` for the Pydantic *models* / schemas

If you want to use your APIs' function names as `operationId`s, you can iterate over all of them and override each *path operation's* `operation_id` using their `APIRoute.name`.

You should do it after adding all your *path operations*.

```Python hl_lines="2  12-21  24"
{!../../../docs_src/path_operation_advanced_configuration/tutorial002.py!}
```

!!! tip

```Dockerfile
COPY ./requirements.txt /code/requirements.txt
```

Docker and other tools **build** these container images **incrementally**, adding **one layer on top of the other**, starting from the top of the `Dockerfile` and adding any files created by each of the instructions of the `Dockerfile`.

```

Here the query parameter `needy` is a required query parameter of type `str`.

If you open in your browser a URL like:

```
http://127.0.0.1:8000/items/foo-item
```

...without adding the required parameter `needy`, you will see an error like:

```JSON
{
  "detail": [
    {
      "type": "missing",
      "loc": [
        "query",
        "needy"
      ],

## The normal **FastAPI** app

Let's first see how the normal API app would look like before adding the callback.

It will have a *path operation* that will receive an `Invoice` body, and a query parameter `callback_url` that will contain the URL for the callback.

So, we get a Pydantic model from the data in another Pydantic model.

#### Unwrapping a `dict` and extra keywords

And then adding the extra keyword argument `hashed_password=hashed_password`, like in:

```Python
UserInDB(**user_in.dict(), hashed_password=hashed_password)
```

...ends up being like:

```Python
UserInDB(
